Tokyo, March 5, 2013 — Casio Computer Co., Ltd., announced today the release of the GB-5600AB and GB-6900AB, shock-resistant watches that can communicate with an iPhone.* These new additions to the G-SHOCK family are next-generation watches equipped with Bluetooth v4.0 (Bluetooth® Low Energy Wireless Technology).

* Compatible with iPhone 4S (iOS 5.1.1 to iOS 6.1) and iPhone 5. To enable connection with an iPhone 4S and iPhone 5, Casio's "G-SHOCK+" application must be downloaded from the App Store.
